What is Rick Simpson Oil (RSO)? What can you expect from it?

Rick Simpson Oil, also known as RSO, is one of the most iconic cannabis extracts available on the market.

The story of its origin and its potential medical benefits are the reasons for its status.

It is impossible to talk about RSO without mentioning the medical benefits that some people believe it has. But, as is often the case when it comes to the medical properties of cannabis, not enough research has been done to prove these claims. Therefore, you should keep in mind that If you are thinking of using RSO to treat a specific health condition, we recommend talking to your doctor first.

Putting its potential medical benefits aside, RSO is also considered the most potent cannabis extract available on the market.

But what is Rick Simpson Oil, how should it be used, how is it made, and what potential benefits might it have? Let’s answer these questions.

Who Invented Rick Simpson Oil?

Rick Simpson Oil got its name after the famous cannabis activist and the RSO inventor himself, Rick Simpson.

Rick, an engineer from Canada, first made RSO when he discovered three growths on his arm, which turned out to be cancerogenic. Having some previous, basic knowledge about cannabis and its potential health benefits, Rick decided to see if cannabis could help him in his fight against this deadly disease.

Rick believed that most of the healing power in cannabis comes from THC. This inspired him to create an oil with extremely high THC content. He then used it as a topical on the parts of his body that were affected by cancer.

After just a few days, the growths disappeared, and Rick’s adventure with RSO began.

He went on living the life of a cannabis activist who made high THC oil for those in need. And not only did he make the oil, but he also provided it for free.

There are many accounts of people who claim that Rick’s THC oil saved their lives or helped them manage pain that required the use of Opioids.

Rick’s doctor never acknowledged the role of cannabis in the healing process, and the accounts of others, who claim to have found the oil to be helpful, are considered anecdotal proof.

How to Consume Rick Simpson Oil

The two most important things to know about consuming RSO are that :

  1. It is most likely the most potent cannabis product you will ever encounter
  2. It can not be smoked or dabbed or vaped, unless specified otherwise


Rick Simpson Oil, also known as Phoenix Tears, should be consumed in tiny amounts. It is recommended for one dosage to be of the size of a grain of rice. Saying that, some experienced users suggest that starting with a dose as small as half the size of a grain of rice is the way to go.

When it comes to using it for medical purposes, it should be taken regularly for at least 12 weeks to help with the condition.

If you are taking it for reasons other than medical, only use it if you are an experienced cannabis user. If you do not have much experience with different cannabis products, especially those with high THC content, RSO is probably not the best product to start experimenting with.

How Much Rick Simpson Oil?

You can take RSO sublingually, as an edible or use it as a topical.

Because of its high flammability, you should avoid dabbing, vaping, or smoking it, unless you bought the product from a trusted producer who made it specifically for those forms of consumption.

When you use it sublingually (under the tongue), you should feel the effects within 10-15 minutes. Make sure you take it slow at the beginning. Taking too much is not pleasant at all.

Adding RSO to food will make the waiting time a bit longer, but the effects might be more lasting than if you take it sublingually. It might take up to 2 hours before you start feeling anything.

RSO has a powerful, earthy flavor and might significantly change your food’s taste. A common way of consuming RSO as an edible is putting it on a cracker.

Using it as a topical is very common, especially among people who use it to combat certain skin conditions. Ideally, it would be put on a bandage or a patch and then placed on the affected area.


RSO has a thick consistency that can make it a bit challenging to use. It is incredibly sticky and gooey, so it is pretty common to get it stuck to your lips or fingers. Fortunately, producers often think of the most comfortable way to consume it, and therefore often sell the RSO in a handy applicator.

How Does It Feel?

Because of RSO’s high THC content, it hits you hard.

Most first-time users say the oil makes them feel extremely tired and sleepy, to the extent where it is hard to go about with your day and complete any tasks that require focus and attention.

Some users say the feeling of tiredness becomes less overwhelming after 4 weeks of regular use.

How Is RSO Made?

Rick believes that every person in the world who needs his oil should have access to it. This is why he was making it for free.

Unfortunately, due to legal restraints, Rick is no longer able to make the oil himself. To continue his life’s mission, he decided to share how to make RSO with the world so that every single person who needs it can make it for themselves if that’s what they want.

Making it does not require complicated equipment. Rick made sure that most of the tools needed to make his oil can be found in any household. But you should be aware the process can be dangerous due to the use of highly flammable ingredients. Do not make it in a poorly ventilated space!

Unfortunately, RSO is still illegal in many places worldwide due to its extremely high THC content. But if you are lucky enough to live in a country or a state where it is allowed, you do not need to make the oil yourself. Instead, you can purchase lab-tested and legal RSO in certain dispensaries.

Does It Work?

The short answer is – we don’t know for sure. Because we are only just coming out of cannabis prohibition, cannabis research is very much behind.

Much more research has to be done, but in order to do that, much more money and time need to be invested.

Right now, researchers are looking into what cannabis can do for human health, including researching THC’s impact on cancer.

Early research is not conclusive, but it is very promising. Tests done on animals that suffered from cancer show THC can have properties that help the body fight cancer, especially when combined with other cannabinoids (the so-called entourage effect).

All we can do now is wait and see.

Where Can you Learn More?

If you are one of many people fascinated by Rick Simpson and his product, there are plenty of places where you can learn more about the inventor and his creation.

Rick’s most famous book, “Phoenix Tears,” is a great starting point for those who want to understand the origins of the oil as well as the story behind the man himself.

Take Aways

Rick Simpson Oil, also referred to as RSO or Phoenix Tears, is a high-THC cannabis concentrate that is exceptionally potent.

The oil gained its fame due to Rick’s story of using it to battle cancer, as well as his cannabis activism.

RSO is still illegal in many places due to its high THC content. It is nevertheless legal to purchase in California, and selected dispensaries (The Source included) make it available for their customers.

While researchers still need to find scientific proof of the health benefits, RSO has a vast group of proponents and, therefore, is not likely to disappear from the cannabis conversation anytime soon.
